The play is set in the tiny principality of Andorra in southwestern Europe. The story revolves around a young boy, Andri, who is brought up as the Jewish adoptive son of the town's Teacher, who claims to have rescued him as a child from the neighbouring, anti-semitic "Blacks" (implying Blackshirts). However, it is revealed during the first half of the play that the story of Andri's origin is a lie: he is the illegitimate child of the Teacher and the Señora, a lady from the Blacks, and Andri is not a Jew. When the play starts, Andri is engaged to the Teacher's daughter Barblin, who he has grown up with and who (unbeknownst to him) is his half-sister. While the Teacher tries to ensure they do not marry, Andri becomes the center of anti-semitism first from his fellow town members and later from invading Black forces. When the Teacher finally reveals the truth, the townspeople do not accept it, and permit Andri to be killed. At the end, Andri identifies with the Jews and defiantly welcomes his fate. --Wikipedia.com.
